Gardner (crater)

Gardner is a small lunar impact crater in the northeast part of the Moon. It lies due east of the crater Vitruvius, in a section of rough terrain north of the Mare Tranquillitatis. This crater was previously designated Vitruvius A before being given its present name by the IAU. To the northeast of Gardner is the larger crater Maraldi.

It is a circular crater with sloping inner walls and an interior floor that occupies about half the total crater diameter. The southern half of the floor has a slight rise before reaching the inner wall. The crater is not significantly eroded, and the outer rim is relatively sharp and well-defined. The most distinctive feature is a row of four rounded hills along the northern floor of the crater.
